Molecular surveillance of the antifolateresistant mutation I164L in imported African isolates of <em>Plasmodium falciparum</em> in Europe: sentinel... (Publications)
BACKGROUND: Malaria parasites that carry the DHFR-mutation I164L are not only highly resistant to sulfadoxine-pyrimethamine but also to the new antimalarial drug chlorproguanil-dapsone. The spread of this [...] network for the surveillance of travel-associated diseases and seems to cover approximately 12% of all malaria cases imported into Europe. Within this network we screened 277 imported African isolates of P.
A simple and efficient tool for trapping gravid <em>Anopheles</em> at breeding sites (Publications)
BACKGROUND: No effective tool currently exists for trapping ovipositing malaria vectors. This creates a gap in our ability to investigate the behavior and ecology of gravid Anopheles. FINDINGS: Here we [...] ecology of gravid female Anophelines. It strongly implies that at least two of the major vectors of malaria in Africa land on the water surface during the oviposition process, and demonstrates that Anophelines
Fast-killing tyrosine amide ((<em>S</em>)-SW228703) with blood- and liver-stage antimalarial activity associated with the cyclic amine resistance... (Publications)
Current malaria treatments are threatened by drug resistance, and new drugs are urgently needed. In a phenotypic screen for new antimalarials, we identified (S)-SW228703 ((S)-SW703), a tyrosine amide with [...] fast-killing mechanism of action, available for lead optimization to generate new treatments for malaria.
Addressing the intracellular vestibule of the plasmodial lactate transporter PfFNT by p-substituted inhibitors amplifies in vitro activity (Publications)
Inhibition of the lactate transporter PfFNT is a valid novel mode of action against malaria parasites. Current pyridine-substituted pentafluoro-3-hydroxy-pent-2-en-1-ones act as substrate analogs with [...] metabolized, the more stable p-acetanilide cleared 99.7% of parasites at 4 × 50 mg kg(-1) in a mouse malaria model. Future stabilization of the p-substitution against metabolism may translate the gain in in
Multiplexed ddPCR-amplicon sequencing reveals isolated <em>Plasmodium falciparum</em> populations amenable to local elimination in Zanzibar, Tanzania (Publications)
Zanzibar has made significant progress toward malaria elimination, but recent stagnation requires novel approaches. We developed a highly multiplexed droplet digital PCR (ddPCR)-based amplicon sequencing [...] genetic structure across the Zanzibar archipelago and provides actionable insights for prioritizing malaria elimination efforts.
The catalytic subunit of <em>Plasmodium falciparum</em> casein kinase 2 is essential for gametocytogenesis (Publications)
pleiotropic kinase phosphorylating substrates in different cellular compartments in eukaryotes. In the malaria parasite Plasmodium falciparum, PfCK2 is vital for asexual proliferation of blood-stage parasites [...] PfCK2alpha catalytic subunit in gametocytes, the sexual forms of the parasite that are essential for malaria transmission. We show that PfCK2alpha localizes to the nucleus and cytoplasm in asexual and sexual
Structure-activity relationships and antiplasmodial potencies of novel 3,4-disubstituted 1,2,5-oxadiazoles (Publications)
The 4-substituted 3-amino-1,2,5-oxadiazole 1 from the Malaria Box Project of the Medicines for Malaria Venture foundation shows very promising selectivity and in vitro activity against Plasmodium falciparum
Mosquito net coverage in years between mass distributions: a case study of Tanzania, 2013 (Publications)
commercial market. To sustain investments and health gains in the fight against malaria, it is important for the National Malaria Control Programme to monitor LLIN coverage especially in the years between mass [...] household survey was conducted in 3398 households in eight districts in Tanzania. Using the Roll Back Malaria indicators, the study analysed: (1) household net ownership; (2) access to nets; (3) population net
Assessment of global reporting of adverse drug reactions for anti-malarials, including artemisinin-based combination therapy, to the WHO Programme for... (Publications)
BACKGROUND: In spite of enhanced control efforts, malaria remains a major public health problem causing close to a million deaths annually. With support from several donors, large amounts of artemisinin-based [...] covering the period 1968-2008. All countries in the programme were clustered according to their malaria control phase and income status. The number of individual case safety reports (ICSRs) of anti-malarials [...] ICSRs suspecting anti-malarials were received from 64 countries....
